Abstract
Background
Neoadjuvant chemoradiation reduces local recurrence in locally advanced rectal cancer, and adherence to national and societal recommendations remains unknown.
Objective
To determine variability in guideline adherence in rectal cancer treatment and investigate whether hospital volume correlated with variability seen.
Design
We performed a retrospective analysis using the National Cancer Database rectal cancer participant user files from 2005 to 2010. Stage-specific predictors of neoadjuvant chemotherapy and radiation use were determined, and variation in use across hospitals analyzed. Hospitals were ranked based on likelihood of preoperative therapy use by stage, and observed-to-expected ratios for neoadjuvant therapy use calculated. Hospital outliers were identified, and their center characteristics compared.
Results
A total of 23,488 patients were identified at 1183 hospitals. There was substantial variability in the use of neoadjuvant chemoradiation across hospitals. Patients managed outside clinical guidelines for both stage 1 and stage 3 disease tended to receive treatment at lower-volume, community cancer centers.
Conclusions
There is substantial variability in adherence to national guidelines in the use of neoadjuvant chemoradiation for rectal cancer across all stages. Both hospital volume and center type are associated with over-treatment of early-stage tumors and under-treatment of more invasive tumors. These findings identify a clear need for national quality improvement efforts in the treatment of rectal cancer.
